Abstract: A method of controlling the diameter of a silicon single crystal. In the course of manufacturing a silicon single crystal (1) by pulling the silicon single crystal while rotating it relative to a crucible (2), a comparison between a measured diameter value of the pulled single crystal measured by optical means (5) and a desired diameter value is made to determine a deviation so that the resulting deviation is subjected to an incomplete difference PID processing or the Smith method processing to calculate (11) a pull rate and the pull rate is applied to a motor controller (8) of a crystal pulling apparatus (7) thereby performing the diameter control of the pulled single crystal through the manipulation of the pull rate. An apparatus for controlling the diameter of a silicon single crystal includes input means for receiving a measured diameter value of a pulled single crystal measured by optical means, incomplete differential PID computing means (11) for making a comparison between a measured diameter value of the pulled single crystal and a desired diameter value a plurality of times at intervals of a unit rotational period to calculate a pull rate, and output means (12) for applying the pull rate to a motor controller (8) of a crystal pulling apparatus (7).

Abstract: An optical fiber cable (20) ideally suited for aerial distribution use, for example, includes in a preferred embodiment at least one bundle (23) of optical fibers (25-25). The at least one bundle is disposed in a tubular member (30) which is made of a plastic material suitable for use in a relatively wide temperature range and which is enclosed by a sheath system (32). A predetermined excess length of fiber is caused to be disposed in the tubular member. The excess length of each fiber is such that it is sufficient to avoid undue strains on the fiber as the cable core is exposed to the elements and to forces imparted during handling such as during installation. On the other hand, the excess fiber length must not be so great as to result in undue curvature of the fiber or excessive interactive engagement of the fiber with an inner wall of the tubular member. As a result of the magnitude of the excess length of the opical fiber, the requirements which must be met by the sheath system are not as demanding as for prior art cables, thereby resulting in a significant reduction in cable diameter and weight.

Abstract: The invention is a process for selectively adsorbing nitrogen from a gas mixture which comprises contacting the gas mixture with an adsorbent that has a moderate nitrogen capacity and a high selectivity for nitrogen over the other components in the mixture. With respect to air separation, improved adsorbents have low O₂ capacity with N₂ capacity at roughly the same level as current adsorbents such as CaA. O₂ VSA computer process simulations have shown the unexpected result that for materials with the same binary isothermal working selectivity, those with lower isothermal nitrogen working capacity are superior O₂ VSA adsorbents, provided that they have a nitrogen working capacity of at least about 0.3 mmol/g.

Abstract: The technical field of the invention is tap water temperature regulation, specifically for the maintenance of a determined - also predeterminable - temperature of tap water on the secondary side, which is heated via a heat exchanger from a primary circuit. To improve the regulation accuracy and for the avoidance of increased regulation deviations, a neural network (30; 40) is used, which controls via a manipulated variable the delivery loading of the delivery pump (9) arranged in the primary circuit. The neural network has two neuron planes (40a, 40b), of which one is an input plane (40a) and one an output plane (40b). To the input plane are fed the desired temperature ( theta s) and the difference  DELTA  theta between the desired temperature  theta s and current temperature theta 25 of the water entering into the heat exchanger on the primary side. Each of the neurons is a carrier of a function (Pi,j). Each of these functions determines a loading P via a flow  PHI , which is detected with a measuring transmitter (19) in the primary circuit. A change of the flow thus effects directly, using the predetermined function Pi,j, a change of the primary load of the primary circuit delivery pump (9), in order to bring the temperature ( theta 18) of the tap water on the secondary side as quickly as possible to a predetermined value and also to keep it constant there in the long term - even in the case of sharply changing tap water flow. <IMAGE>
